To all whom 'it 'may concern:

Be it known that l, WALLACE M. WAL- CUTT, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have invented new and useful Improvements in Hot-Tater HeatingSystems, of which the following is aspeciiication.

- This invention relates to certain new and useful improvements inhot-water heating systems, one of the objects in view being to providemeans whereby each radiator in the system will be equally and quicklysupplied with water from the main, and pro er discharge of the watertherefrom allowe without restricting the lowof the water through themain or its supply in like ratio to the other radiators. v

A further object of the invention is to provide a means by which theresult sought may be accomplished in a sim le and effective manner, andwhereby the ce feed of the water from the heater to the radiators andreturn of the same from the radiators to the heater will be insured.

A still further object of the invention is to provide a construction by'which a radiator may be shut off or cut out without affectingV the flowin the circuit at the point adjacent the radiator or through thebranches by which the radiator is supplied, so that, upon the subsequento ening of the valve governing the su ply ofpwater to the radiator, the

. latter wil be at once lled and quickly heated, thus enabling a rom orapartment 'from which the heat has been cut ofi to be ra idly warmed.

Vith these and other ends in view, the invention consists of thefeatures of construction, combination and arrangement of partshereinafter fully described and claimed, referenoe being had to theaccompanying drawing, in which Figure 1 is a view showing the embodimentof the invention in a down-feed system. Fig. 2 is a view showing adiii'erent mode of arranging the radiators. showing the embodiment ofthe invention in an up-ieed system. Fig. 4 is a detail section throughone of the radiator valves. Fig. 5 is a cross-section through the valveper se.

Referring to the drawings, and particularly to liigs. 1 and 2, 1designates the llow or supply portion and 2 the return portion of themain or circulating ipe, between which are arranged the brano es orlaterale 3 for Fig. 3 1s a view supplying the respective radiators 4.The branches or laterale are shown as each consisting of branches 5 and6 connecting res ectively at their upper and lower ends with tlieportions 1 and 2 of the main and connected at their roxirnate ends by areducing pipe section 7 isposed opposite the radiator 4. The saidsections 5, 6 and 7 are coupled by tees 8 and 9 from which lead supplyand discharge branch pipes 10 and 11 tothe u per and lower portions ofthe radiator, T e reducing pipe section 7, having less area than thesections 5 and 6, acts as a choke limitin the feed area of the lateralas a whole, an operating to divert a portion of the water on itsdowniiow therethrough thro'u h the supply connection into the radiator,rom which the water dischar es through the connection 11 into the lowerthence enters, the main.

Arranged between the supply and discharge branches 10 and 11-is a pipe12 forming a by-pass, throu h which, when the Water is out off from tu eradiator, the supply normally diverted thereto through the action of thereducing connection 7, will be conducted by said b -pass to the lowerbranch of the lateral. This by-pass pipe has an area equal to'the-difference 1n area between the branches of the lateral and reducingportion 7 thereof, and operates when the radiator is shut off as acompensating pi e allowing the full amount of water to'flow t ough thelateral as though the radiator were in operation. The by-pass andconnection 10 are controlled by a valve device comprising a casing 13provided with branches 14 and 15 communieating respectively with thecoupling 8 and radiator 4 and a branch 16 communicating with the upperend of the by-pass l2. The

return portion 2 ofthe branches 14 and l5 are separated by a partitio'n17 having a port 18 and formed Qn its underside with a valve seat 19,below which the connection 16 is formed to provide a formed with athreaded opening closed by a cap 21 in which operates a threaded stem 22ranch -3 of the lateral and 100 valve seat 20. The top of the casing is'the lower headed end 27 of the stern, by which the valve and its stemare clamped against independent movement.

When the valve is moved upwardagainst the seat 19 the port 18 is closed,thus cutting ofi the supply of water to the radiator, the water divertedinto the connection from the upper branch 5 of the laterale by the redueiug section 7 passing downward through the luy-pass l2 and thence outthrough the discharge connection 1l into the lower branch 6 of thelaterals and finally into the return portion 2 of the main, by which anuninipeded iiow of the normal quantity of water past the cut outradiator is secured.

When the vaine is moved downward lto enn `gage the seat 20,communication between lEil the lateral audupper end of the by-pass iscut ofi and conununication between the lateral and radiator established,4so that the from becoming cold or airbound when the radiator vis cutout, and providing lor the immediatelliow of water' to the radiator assoon as the valve is opened, so that the radiator will become quicklyheated. n The sarnegeneral construction is ern loyed in the disclosurein Fig; 2, in which a di 'lerent Verrangement ol the radiators is shown,a pair oi radiators beine coupled to the sume lateral or supplybrancn'at'opposite sides of the same through a duplicatlon of the. flowconnection liereinhei'ore specified;

` ln the embodiment of the invention in an up-feed system, asillustrated in Fig. 3, the

supply branch 5 of the lateral-is in the form of a riser connected at.its upper end directly by the valve casing 13'l 'wit 1 the sup ly con-1 nection l0 and by-pass 12., which atter is connected at its lower endby a coupling 9a' with the dischar e connection 11 and upper end ofthereturn t, ranch a ci' the lateral, the lower ends, of the pipes 5 and 6beingre: spcetivelv connected Vwith* the sections 1a and 2a of the mainby icouplings 28 and 29, between which'is arranged a lreduced p esection 30. vThe 1(portions la and 2*- of tlie main operate, so ar asthe` articular radiafor in question is concerne as the supply and returnportions of such main, and the pipeBO. as the equivalent of the reducingpipe 7 in the construction disclosed in Figs.

1 and 2 said pipe 30 lrestricting the area of the main at the pointbetween the inlet and discharge/ portions of the lateral to choke theilow of water andcause a portion to be di' verted through the-.branch 5to the radiator when the va ve. isfo en, the water returning inallythrough thef ranch 6'B to the main on the oppositeside of the pipe 30,as will be comme readily understood. When the `valve is closed the waterdiverted u ward through the pipe -5l flows downward t rough the bypass12 into the pipe 6 and thence to the lateral upto the top thereof, sothat upon simply opening the valve the `radiator will be instantly suplied and quickly heated. As shown, the ljaterals of the radiatorsarranged upon the dille/rent loors extend upward from the main and areprovided throughout with the by-pass connections and are separated attheir points of connec-y tion with the main by a reducing or choke ipe,whereby the water is'caused to i'low trom radiator to radiatorthroughout the systeni, thence to theheater for` recircula-V` tion.

lt will be seen from the foregoing description that all ci the'radiators when o enjwill be equal-ly and uickly supplied wit water fromthe main in ike ratio without restricting the normal iiow of the waterthrough the main and that the laterale or su pply branches will beflie tfull of hot water up to the height l.

vfor any period of time unwarrned through the cutting out oi itsradiator from the syste il@ It. will be understood, of course, that whthe yyerms laterale or branches a used'as in the art for speciallydesignatin the portions ofthe piping leading from anu. to or between theportions ol a main or feed pipe for conducting the water to and from thcradiators, the invent-ion is not limited to the speci'lic constructionand arrangement of parts herein shown in either form of the inventionfor effecting the supply of water to each radiator and its returntherefrom, vand I also do not restrict myself to any particulararrangement of the flow reducing or throttling means for diverting aportion ol" the water flowing through a portion of the system into aradiator.
